    摘要： A viewing angle control panel (2) that includes two substrates (4 and 6) facing each other and liquid crystal layer (5) provided between the substrates and that is usable in combination with a display panel (10) so as to allow a liquid crystal display device (1) to switch a viewing angle characteristic, wherein: one of the substrates (6) includes a counter electrode pattern (62) in which a counter electrode is provided over the one of the two substrates; and the other one of the substrates (4) includes a transparent electrode pattern (49) in which transparent electrodes (49a through 49d) are provided in a striped manner and first and second wire electrodes (e.g., wire electrodes 48a and 48b) that are provided for each space (e.g., a space 51x) between the transparent electrodes in the transparent electrode pattern (49) in such a manner that the first the second wire electrodes, positioned in parallel with the transparent electrodes, respectively, overlap the space 51x. In the arrangement, electric potential settings of wiring electrodes (48a through 48f) are changed. This makes it possible to switch a visibility limitation direction.

    摘要： A liquid crystal display device includes a reflective liquid crystal panel (20) having a liquid crystal panel polarization plate (22), a polarization plate (32) provided on a front surface side of the polarization plate (22) with its absorption axis in parallel with an absorption axis of the polarization plate (22), and a negative C plate (31) provided between the liquid crystal panel polarization plate (22) and the polarization plate (32). The negative C plate (31) sets a direction in which viewing limitation is carried out. Thus, it is possible to provide the liquid crystal display device in which a viewing angle can be narrowed by freely setting, in the reflective liquid crystal panel, the direction in which the viewing limitation should be carried out.
